Wall St Engine summarised the filing on X: compute and infrastructure spending up 382% year over year in the third quarter, against 300% in the second; $895.4 billion of commitments, with $447.5 billion due before 2031 and $69.8 billion within 12 months; and $131.9 billion of cash and short-term investments. The 382% is in the filing; the 300% matches our arithmetic from its quarterly table, and the $131.9 billion is the sum of the filing’s $95.6 billion of cash and $36.3 billion of short-term investments.
Anthropic expects about $69.8 billion of its compute and infrastructure commitments to fall due in the 12 months after 30 September, according to the amended Form S-1 it filed with the SEC on Monday, 2 November. The amount is part of approximately $895.4 billion of purchase commitments and lease agreements, substantially all related to compute and infrastructure. These are Anthropic’s own spending obligations, not customer contracts.
The 12-month amount is about 1.03 times Anthropic’s third-quarter revenue pace of $67.8 billion a year, by our arithmetic. The filing also says about $213.8 billion of its contractual obligations is subject to termination rights or contingent conditions.
The key insight: Anthropic’s amended S-1 lists about $895.4 billion of its own compute and infrastructure commitments, $69.8 billion of them due within 12 months, and says about $213.8 billion is subject to termination rights or contingent conditions.
What the Filing Commits Anthropic To
The filing says that as of and after 30 September, Anthropic has entered into “purchase commitments and lease agreements, including short-term commitments, as well as leases not yet commenced, with an aggregate committed spend of approximately $895.4 billion, substantially all of which is related to compute and infrastructure”.
It adds that these commitments include “approximately $447.5 billion expected to be incurred before December 31, 2030, and substantially all of the remainder is expected to be incurred between 2031 and 2045”, and that “approximately $69.8 billion of these commitments are due in the 12 months following September 30, 2026”.
By our arithmetic from those figures, about $377.7 billion falls due between the first 12 months and the end of 2030, and about $447.9 billion afterwards.

The $213.8 Billion That Could Fall Away
The filing says “approximately $213.8 billion of the aggregate total of our contractual obligations relates to arrangements that are subject to either exercisable termination rights or contingent conditions prior to commencement, such as the counterparty’s ability to secure financing, facilities, or regulatory approvals, as applicable”. “If those conditions are not met, the arrangement may be terminated”, it adds.
That is about 24% of the $895.4 billion total, by our arithmetic. The filing also says that where counterparties miss agreed delivery dates, Anthropic can in general terminate all or part of its obligations or obtain other remedies such as service credits.
Against $95.6 Billion of Cash
As of 30 September, Anthropic had cash and cash equivalents of $95.6 billion, $36.3 billion of short-term investments and $14.8 billion available under its credit facility, the filing says. The $69.8 billion due in the next 12 months is about 48% of those three amounts combined, $146.7 billion, by our arithmetic.
The filing’s risk factors say the commitments “may substantially increase our operating expenses and cash requirements” and that “these expenditures and investments may be more costly than we expect”.
Compute Spending Was Already Rising
Compute and infrastructure expense was $9,863 million in the third quarter, up 382% from a year earlier, the filing says. In the second quarter it was $5,558 million against $1,390 million a year earlier, a 300% increase by our arithmetic from the filing’s quarterly table.

Business Pill: A Cost Test — why a committed cost and a paid-for cost are not the same thing.
As we read the filing, the near-term figure is the one that meets the balance sheet: $69.8 billion due in 12 months against $95.6 billion of cash, $36.3 billion of short-term investments and $14.8 billion of available credit.
As we read the $213.8 billion, about a quarter of the total is subject to termination rights or contingent conditions, so the headline commitment is not a single fixed bill.

Three Implications
FOR IPO INVESTORS The filing says the commitments may substantially increase Anthropic’s operating expenses and cash requirements, with $69.8 billion due in the 12 months after 30 September.
FOR COMPUTE SUPPLIERS The filing says about $213.8 billion of the obligations are subject to termination rights or to conditions such as the counterparty securing financing, facilities or regulatory approvals.
FOR LENDERS The filing reports $95.6 billion of cash and cash equivalents, $36.3 billion of short-term investments and $14.8 billion available under its credit facility as of 30 September.
The framework says: “The $1T capex cycle is being underwritten by a $1T concentrated demand commitment from two counterparties whose combined free cash flow is deeply negative.”
As we read it, Anthropic’s filing now puts a figure on one side of that argument: about $895.4 billion of its own committed spend, substantially all on compute and infrastructure. The framework is the owner’s argument and does not discuss this filing.
The filing gives the total and three time buckets, not a year-by-year schedule for all $895.4 billion, so the split between the 12-month figure and end-2030 is our arithmetic. The 1.03-times comparison sets one year of obligations against one quarter’s revenue pace, which is our annualisation, not a forecast. The filing does not say which counterparties hold the $213.8 billion of terminable or contingent arrangements.
This Week In The AI Supercycle
Anthropic’s Reality Check, The Capital Squeeze, & The New World Order
This week’s issue: for two years the AI build-out was priced as a growthstory. This week it started being priced as a credit story.
Anthropic’s amended S-1 lists about $895.4 billion of its own compute and infrastructure commitments, with $69.8 billion due in the 12 months after 30 September and $447.5 billion before the end of 2030. About $213.8 billion is subject to termination rights or contingent conditions, and Anthropic reported $95.6 billion of cash and cash equivalents and $36.3 billion of short-term investments at the end of September.
A note on sourcing. All figures and quotations are from Anthropic’s amended Form S-1 filed with the SEC on 2 November 2026. The $67.8 billion revenue pace, the 1.03-times comparison, the $377.7 billion and $447.9 billion buckets, the 24% share, the $146.7 billion liquidity total, its 48% share and the 300% second-quarter rise are our arithmetic.
